Research Of Data Integration And Application Of Oceanic Ecological Environment Monitoring System

The 21st century is new times for humanity to develop and utilize marine, whose theme is sustainable development. Using marine scientifically, reasonably, orderly can solve the problems of population explosion, lack of resources and environmental deterioration. Costal areas are rich in natural resources, as the most developed zone, are faced with the unprecedented environment-ecology stress in recent years. To guarantee economy sustainable development, the country attaches more importance to marine ecology environment. Obtaining and analyzing marine eco-environmental monitoring data, knowing about the present situation and dynamic change trend of marine eco-environment and early warning and forecasting marine emergency is the foundation and precondition of marine ecology environment protection. Our country starts to monitor the marine environment from sixty decade last century in succession. Especially for the nearly three decades,, the prototype of three-dimensional monitoring network composed of marine station, buoy, survey ship, satellite remote sensing and aviation remote sensing is initially builded up along with the development of marine economy and growth of China's national power. Especially during the period of the nineteen ninety-six to two thousand and two thousand one to two thousand five, on the support of 863 plan, a large amount of scientific and technical achievement springs up, which improve research level of our country marine monitoring system.The object of the manuscript is the integration application of marine environment monitoring data, aiming at the characteristic and application need of marine synthesize monitoring system composed of various of marine environment observation system, combining with the interrelated subject. The research concentrates on monitoring data transmission, integration, database management and data analysis and evaluation. The target is to build the effective method system and technique frame for marine eco-environment monitoring data integration and application. The study path is in the order of monitoring system, data, transmission, integration, application, practice and perfection. The system study and discuss the data transmission and integration technology of various monitoring system, the integration of marine eco-environment monitoring data, automatic analysis and evaluation of GIS(geography information system) data and the application of monitoring data integration system. The research and achievements are as follows:i the transmission and integration of marine eco-environment monitoring systemThe special object and environment of marine monitoring system result in its transmission way is different from the command data transmission.It studies the merits and faults of present data communication and transmission. The system solves the problem of how to design different data transmission network suitable to every marine environment monitoring system based on the characteristics of various marine environment monitoring system and the distribution situation of related ground handling station combining with the characteristics of marine monitoring system. The system achieves the data automatic transmission of eco-environmental monitoring system. It designs and develops the transmission and integrated system of monitoring data, completes the automatic acquisition and preservation of marine environmental monitoring data. By the practice and improvement of data transmission and integration system, the system provides the users complete and practical method and project about various marine environment monitoring system data transmission method and data integration.ii establish a set of data storage management suitable for marine environment monitoring dataThe integration of marine eco-environment monitoring data is the important content of the research. The data isomerism is the most important issue of marine environment data integration. The paper has deep analysis on the characteristics of marine environment monitoring data and integration technology features of database, integration middleware and XML et al. It discusses the feasibility of construction marine environment monitoring data warehouse using the above technologies. It gives the construction process and methodology of every monitoring database. The developed marine eco-environment monitoring database system and the integration technology provides convenient and efficient tool for various marine monitoring data management, import and export, and realizes the unify of organization and management of marine eco-environment based on data warehouse and spatial data.iii the analysis and application of monitoring data based on GISThe integration of marine eco-environment monitoring data is to meet the need of marine environment monitoring operation and marine management, and realize the function of marine data analysis, evaluation and warning, forecast of marine disaster. According to the need of application service, the paper studies spatial and temporal models and related evaluation techniques suitable for the marine environment characteristics based on the above research achievement. It constructs the marine environment monitoring data analysis and evaluation system based on GIS and realizes the function of monitoring data automatic analysis and evaluation. The related research achievement are improved in the follow-up monitoring and warning system for key areas and Qingdao Olympic sailing field of red tide and achieves good results. It verifies reference example sense of research achievement for different marine environment monitoring system construction and operation, the application practice promotes the continuous improvement of research results in turn.The research constructs and practices the technical solutions and methods for marine eco-environment monitoring data integration, management and application. It provides the technique research foundation and application example for constructing new marine eco-environment monitoring system.
